pH

Question 1

What is the pH scale?

Answer 1

A scale from 0-14
(0-7=acidic) (7-14=basic)
7=neutral

Question 2

What is an acid?

Answer 2

• has lots of hydrogen
• lowers pH

ex. Hydrochloric acid (HCl)

Question 3

What is a Base?

Answer 3

• has OH ions
• raises pH by recuding H ions

Question 4

What does pH measure?

Answer 4

the amount of hydrogen
p=potential
H=hydrogen

Question 5

Where in the body can you find a basic enviorment?

Answer 5

Blood ~ 7.4 pH
Small intestine ~8.4 pH

Question 6

Where in the body can you find an acidic enviorment?

Answer 6

The stomach

Question 7

What is a fucntion of acid in the stomach?

Answer 7

aids in digestion of proteins

Changes shape of enzymes active site so it no longer fits the substrate

Question 8

What is an enzyme?

Answer 8

• A catalyst for chemical reactions in the body
• a protein that helps speed up metabolism
• must be kept at ideal pH or a structure change will occur

(catalyst for essential processes in the body)

Question 9

How does an Enzyme work?

Answer 9

An enzymes active sight accepts “substrates” which are then turned into products

Question 10

What is a buffer?

Answer 10

It picks up or realeses hydrogen/hydroxyde to maintain “Homeostatis”

Homeostatis= body process to keep it steady and always adjsuting

Question 11

Why is it important ot maintain pH?

Answer 11

• human body places have diff pH
• if pH changes enzymes will change shape
• Affects funciton of tissues and organs
• death or severe illness

Question 12

What does denaturing mean?

Answer 12

Denaturing is the process of changing enzymes shapes reulting in them unable to funciton

they change shape through temperature
